A little while back Zenmaxxor, AE and myself had a quiet little chat about bows, obsidian heads and arrow weight. I stand by what I said when applied to bows in general in SR, but no longer for Ranger-X bows.

I really should have read the fluff about it. It specifically states that this bow is of SOTA materials and designed to work with a Ranger-X arrow. This arrow is constructed from specialist polymers to form a more rigid and lighter arrow. The arrow itself is described as traveling faster and further.

After checking the damage/range tables I found that this is not the case in my version of the book. Has it been erata-ed anywhere?

MPO - The range of a Ranger-X should be 20%-25% longer than an equivalent STR bow and +1TN# penalty for using the RX bow with any arrow other than a RX arrow. Due to the much lighter weight of RX arrow, none of the specialist super-heavy arrows we chatted about would work without additional accuracy/power problems.

Thank you.

I think that my major issue with the whole Ranger-X business is that it is completely unnecessary. The compound bows we have right now can be acquired in really quite insane poundages (evil looking techno-bastard things they are, too, like terminator skeletons), and the arrows are of truly negligible weight. And contrary to popular belief, the heavier bows are not necessarily better for the task overall.

There's a rather good American bow hunting site that covers this here . To quote one small section:

QUOTE
The truth is, many guys just can’t resist their "He-Man" impulses to try to shoot heavyweight bows. If you’ve ever visited a busy archery shop, you’ve certainly noticed guys who seem determined to prove their super-human strength by yanking and jerking these 70+ pound bows until they're on the verge of a hemorrhage. In spite of the strain, most guys will still choose bows which have too much draw weight. Some compound bows are available up to a 100# draw weight. While these bows will produce remarkable penetration on a target, they will not necessary produce faster arrows speeds or flatter trajectory. Since these bows must shoot arrows which are very stiff and heavy, they rarely outperform their lower weight counterparts

The important part in that quote is

Correct choice of arrow does give these heavier bows an advantage, and the special Ranger-X arrows are just this.

Actually, the important part in that quote is
QUOTE

This implies that "stiff and heavy" arrows are the correct choice for bows with a heavy draw weight.

I would contend that the article is semantically incorrect, and that it must shoot arrows which are very stiff, and that with today's technology that inescapably leads to arrows which are heavy. This interpretation would allow advances to lead us to the Ranger-X.

Although in RL it is more correctly

"Have the stiffness and weight suitable for the poundage."

After years spent on the archery field I would love somebody to show me how a 45lb field bow can be as accurate or have as long a range as a 86lb compound bow.

Historically, if you were going into battle with a 70lb longbow people would be asking which debilitating illness you had suffered from to still be using a "kiddie's" bow.

Also from the same refence site quoted

QUOTE
Draw Weight - Effect on Arrow Velocity

High poundage bows require heavier, stiffer arrow shafts. Lower poundage bows can use lighter, more limber arrow shafts. IBO standards allow 5 grains of arrow weight per pound of draw weight. So a 70# bow should not shoot an arrow weighing less than 350 grains. A bow set for 60#, no less than 300 grains and so on. Shooting an arrow that is too light for the bow’s draw weight setting has a similar effect as dry-firing the bow and can result in eventual bow damage. In addition, violating IBO’s minimum arrow weight standards would cause you to be disqualified at an IBO 3D event. That much said, the fact is that arrow weight has a dramatic effect on arrow velocity. Lighter arrows fly considerably faster, heavier arrows much slower. Surprisingly, when set for IBO minimum standards, many bows are only fractionally faster in the 70# version vs. the 60# version. Since a 70# bow will need at least a 350 grain arrow, and a 60# bow can use a lighter 300 grain arrow, the savings in arrow weight offsets the loss of energy storage during the powerstroke. Properly set-up, a 60# version of most bows will perform within 10 fps of the heavier 70# version.


the above says an officially measured arrow for a 70lb bow travels 10fps faster than a 60lbs in contradiction to the start of the page and ...

QUOTE
Kinetic Energy:  Arrow Mass & Arrow Velocity

How much penetration, or knock-down power, your arrows will have is a matter of kinetic energy.  Arrows which impact the target with more kinetic energy will penetrate the target more deeply than arrows with less kinetic energy. Kinetic energy is the energy of motion.  Any object which has motion has kinetic energy.  Total kinetic energy depends upon two variables: the mass of the object and the speed of the object.  This is more an issue of arrow selection than bow selection, but an important issue nonetheless - and another of those "trade-offs" to consider.  A bow is generally more efficient, and somewhat quieter, when launching a heavier arrow.  But since lightweight carbon arrows are all the rage, we decided to conduct a test to see if the extra speed was really paying off for hunters.


Carbon fibre arrows are lighter than aluminium or solid wood for the same stiffness, they fly flatter and faster to the target. Carbon fibre/alu core arrows take this trend even further. If you read the whole page the statement that heavy bows have no benefit you will see it contradicted throughout. The real point about very high poundage bows is that you have to be very, very strong to use them accurately.

The article may indeed be semantically incorrect - indeed, it almost certainly is. I was merely commenting on what it said, rather than whether it was right or not.

[Sarky]It seems to work fine for interpreting SR rules...[/Sarky]

You put an incorrectly worded document (that has little internal consistency) in as a rationale for a missing SR rule? :eek:

Ahem...no.

[derail thread]
I noted that the WORDING of the document was perfectly consistent with a certain meaning. Whether or not that meaning had any bearing or not upon common sense, or indeed reality, was not the point.

I meant to imply, by analogy, that this is *cough*occasionally*cough* the case with the rules of Shadowrun.

Sorry, again. I've only just noticed that it wasn't you who actually posted the link.

:dead: Quick, men pass the gallon of coffee I think we've got some problems heading our way. :eek:
